Title: Extensive Gear Lube Study
Post by: BigMike on December 21, 2010, 03:38:38 PM
Hey Bill,

Here is the independent study I was telling you about that has convinced me to stop using Royal Purple:

A Study of Automotive Gear Lubes (http://www.amsoil.com/lit/g2457.pdf)

Out of 14 lubes tested, Royal Purple finished 3rd from last. I've been a proponent of RP since 2003. I have it in my truck (both axles, all three transfer cases, and transmission) and I've also been running it in my MR2. Not any more :nope:

Thanks
Mike
